No I don't actually. But I see them as operating in a context in which ``side effects'' are desirable. I of course considered the possibility that the call ``arimaSS(x,mod)'' was there for an induced side effect, but since that sort of thing is generally considered very bad R programming I dismissed the notion out of hand. cheers, Rolf Turner
